' T all whom it may concern:

. necessarily be made of thin sheet-metal, and

Be it known that I, JOHN H. GILMAN, a citizen of the United States, and a resident of Ottawa, in the county of Lasalle and. State of Illinois, have invented certain new and useful Improvements in Flexible spouts, of which the following is a full," clear, and exact specification.

My invention is concerned withcertain improvements in extensible grain spouts, and is designed to overcome some of thedifliculties that have been met with in the prac- As they have been constructed prior to my invention,

tical operation of these devices.

the straight portion (as distinguished from the elbow portion, which can bend) has been made up of solid tubular'sections, and in order to make them properly su port each other whenextended 1n 9. su bstantially straight tube, as is necessary where the spout l-ies anywhere near laterally in discharging grain therethrough, it was necessary to make the tube sections in the form of true cylinders of gradually increasing diameters from the top to the bottom sections, so that they would fit snugly. But the sections must in the severe use to which they are subjected, they soon became dented, and would not then telescope readily. To overcome this difi'iculty, I have made my present invention, and in carrying it out, I employ sheet-metal sections which are preferably slightly conical in form (although they might be truly cylindrical,) and which are expansible and con tract ible at their receiving ends, so that they can be expanded to permit the sections to be telescoped, and contracted when the sections are extendedso' as to secure them firmly into a substantially rigid tube. T 0 this end I make each section with its overlapping edges riveted only at the bottom or discharge end and with a tightening'clamp at its upper end,

the lower end of the section aboveit, and '1 "preferably make the clamp adjustable, so

thatthe tension it exerts can be varied as desired..

To illustrate my invention, I annex hereto two sheets of drawings, in which the same reference characters "areused to designate identical'partsin all of the figures, of which}- 7 Figure 1 a'sijdefelevation of a telesco s out embod my invention, secure ,to 'te dischargegfen [of elevator; Fig. 2 18% vertical section on the line AA of Fig. 1; Fig. 3 is a front elevation showing the spout deflected to the. right in full lines, and to the left in dotted lines; Fig. 4 is a view showing the spout telescoped as it would be in movi it from place to place; Fig. 5 is an invertplan view, on'an enlarged scale, in section on the line BB of Fig. 3; Fig. 6 is a detail in sectionon the line CC of Fig. 5; 7 a top' plan view, on an enlarged scale, of-one of the sections; Fig. 8 is a front elevation, on-an enlarged scale, showing one of the sections clamped upon the adjacent section; and Figs' 9, 16) and -11'are details-showing two modified forms of the clamping mechanism.

I have shown my inventlon as applied tov the head 12 of the upper end of an elevator 11 of the portable t pe, althou h, of course, it will be'understoo that it elsewhere. In ap lying it to such a head, I secure on the disc ha'rge end 12 of the head the downwardly projecting annular flange 13 ,through which end 12 pass the hooks 14, which can be turned into and out of position to engage with the horizontal, annular flan e 15, which is preferably formed from a strip of angle iron secured to the interior of the upermost section 16, which is of.cylindrical orm and-of sheet metal. The adjacent sections 17, 18. and 19 form the elbow portion of the spout, and are conical in shape, so that the spout can be flexed at this point, in the customary manner. In order to telesco e these sections, they are provided on-each si o with the rings 20' to which thechains 21 are secured, as is customary in this class of devices. To the lowermost conical section 19 is preferably rigidly secured the cylindrical section 22 which forms the first sectionof the straight portion of the spout.

scribed is old and well own, and form's no part of my present invention.

As I have previously explained, in prior similar structures, zthe-vtelw'coping sections t be applied The portion ofthe a paratus thus far debelow the section 22 were true cylinders, and

most'to the lowest one .so that they could telescope freely and yet be tight enough to form a tolerably ri id tube when they were they increased in diameter-from the upperextended. It 1S 0 vious that these tubes, 1

tojdistribute grain alon the length of a. crib to the top of which thee evator extends. To overcome this difiiculty, instead of making The lower lsectionsf23 slp'llid'io I secure1 the overappmg ec ges pre era y j y a sing e rivet 24 at the bottom, although they might be riveted-fora considerable distancefrom the bottom towardthe top, althoughsuch a struc- ,to the short arm thereof the link 27'which passesthrough the outwardly-projecting portion of. the ear 28, the curved base-portion 2 9 of which is pivoted to the pipe on the oppo site side of the seam fromthe base plate 25 to allow the link27 to swing. as the lever 26 is 'swung from one position to the other. -Or

the'same. result might beobtained by riveting the ear 28 to the pipe and making the gaperture in the'ear 28 enough larger than link 27 to permitthe necessary play. 'The end of the link 27 passing through the ear 28 'is referablythreaded, as shown, and pro;

vi ed with the nuts 30 and 31jon either side of the ear, so that the tightness ofthe clamp may be, readily regulated. a yielding clamping pressure is desired, I may employ thesubstitu'te shown. in Fig. 9, where for the.

nut '30 I substitute a fixed nut orabutment 30, and interpose between this nut 30 and.

the car 28 the helically -coiled. ex anding spring 30. Instead of having the ever 26 swin verticallfi'I may pivot iton an out war yrojecting ear 25, as shownrin Fig. "10, so t ethe lever canfswingI horizontally,

instead of vertically.- 'Il1 bot cases, it will vbelnoted that the lever swings the link 27 past the center in epening and closing, so that it is securely hel in either osit1on.

In Fig. 11, I illustrate a furt er, but less.

desirable modification, in which the two sides are connected merely by a threaded rod and nut, which accomplishes the same urpose, but in a less convenient and quic y operated structure. 7

While the sections 23 might be true cylinders', with the larger ones at the bottom so that they will telescope, I preferably make them very slightly conical, with the smaller end at the 'bottom,-as theirexpansibility ath. panlon sectlonwith which the expanslble the top will permit of them nesting as muc as is necessa 'to'shorten them when the spout is close Of. course, the sectlons 22.

r and 23 will be provided with the customary eyes 32 and the chains 83 connected thereto in the customary manner to hold the sections.

' together whether they be telescoped or extended. v 4

The operation of the a paratus'wlll be readily understood? The e evator' is moved up alongsideof the crib, and .the extended spout is directed to some ortion of the crib,- and after that portion 15 ed, 1t isswung 1nthe necessary direction to fill another portion, and soon. During the filling operation, the spout can be shortened or extended, as is necessary, and when it is to be removed toanother crib, it, of course, will be telescoped so as to make it short and readily handled. When the straight part is extended, the levers 26 are swung to their:

clamping position, and the sections 23am 1 then clam ed together so as to form a sub-- stantially rigid tube.

While I have shown and described in desire to be limitedin the interpretation of vention. as embodied in the form which I at I the following claims except asmay'be ne-I cessitated by the state of t e prior art.
